How to use Heroku eclipse plugin ? An error encounter

Question

I am using Heroku eclipse plugin to create a Heroku template. Sorry that I am quite a beginner in Heroku and Maven build. I totally don't know how to use Heroku belt tool to build and push the app to server, so I choose eclipse plugin. Now I encounter an error right after I create a Heroku template:

maven-dependency-plugin (goals "copy-dependencies", "unpack") is not supported by m2e.  pom.xml /herokutesting123123    line 48 Maven Project Build Lifecycle Mapping Problem

What could be the problem?

One more problem is how am I going to run the program? Which one should I choose below to build? I thought it should work like how am I working with Tomcat, but I cannot find "run on server" function in the list below. How?

Last problem is how am I going to push the app to the server? I already got the API key after I key in account and password, but I cannot find any function in eclipse to push the app to the server. I thought it work as simple as Google App Engine, one click will do. So, how can I push the app?

Answer 1

You can ignore that error. It's a bug in the Maven Eclipse Plugin. To run the app from Eclipse, see the webapp-runner instructions:

Answer 2

As James mentioned, that is a bug with the Maven Eclipse plugin, but if you want to get rid of the error, you can add an exclusion similar to this in your pom.xml 's pluginManagement section:

As far as your second question, you deploy the app to Heroku via git push . See this doc for details how to do that from Eclipse:
